Realization of the WAT Core in i-WAT

3. Redemption

Suppose that finally, Cameron asked Alice to give her delicious eggs. Alice will get her i-WAT ticket back by repaying the debt.

1. Cameron sends Alice a use message.
2. Alice sends Cameron an approve message.

As the result of this, the i-WAT ticket drawn by Alice is now given back to Alice from Cameron, and its lifecycle closes.

• Alice needs to have the trusted public keys of all participants appearing in the lifecycle of the i-WAT ticket.
  • She does not need to have them all ready when she draws the ticket, but she can collect them on the fly.
